It's not particularly convenient to have to manually modify LocalSettings.php every time one wants to add/remove an extension or change other basic settings. It seems like it would be easier to allow this to be done through a system similar to the System Messages screen. We could have checkboxes for all presently installed extensions, and a checkbox next to a one-line blank form (for allowing entry and installation of new extensions), and an update button. Perhaps a new type of user (in addition to Sysop, Bureaucrat, Oversight, etc.) could be created for doing these major configuration changes.

Also, we might consider adding libraries of commonly-installed extensions (e.g. ParserFunctions, Cite, etc.) so that the user can just select those checkboxes if they want to install it.
